Hello, @It,
Unfortunately, it is not possible to add the chat icon to the bottom menu in mobile without extra customization.
However, you can use custom CSS code to change its place to just above the mobile bottom menu.
Please copy and paste the following CSS code to XStore >> Theme Options >> Theme Custom CSS >> Global CSS and check back to your site after clearing the browser cache:
.crisp-client .cc-tlyw .cc-kxkl .cc-nsge {
margin-bottom: 50px !important;
}
The result should look like this: https://postimg.cc/dkZQGJGM
